Question Brava 1.2 16v 2000 Engine Problems

Hello,

This is my first post after looking for some advice

Recently, i have brought a fiat brava 1.2 16v.

But after driving for about 10 minutes, the car seems to have a bad idle and stall when i come to a stop.

Also while driving the vehicle the car has poor acceleration and struggles and splutters..

when the car is in neutral the car revs to 2000 rpm, then loses power and drops to 900 - 600 rpm and then engine struggles and stops

I have recently changed the spark plugs an Crank sensor...

I have no engine lights come on either..

Starting to lose my nut with it,

So any help would be greatly appreciated

Regards
Ian

Hi Ian,
and welcome to the forum,

so the engine management light does not come on..?,
does it illuminate during the bulb-test at start-up..??

I think your rev-related issue is quite commonly the MAF / Throttle body,
but that often happens when first starting.. is yours only when it gets warmed through..??,
maybe do a search of "throttle-body" = in the Punto section ( same tech),
pretty sure there is a "how-to" in the guides too..!!,

Charlie

Erm.. the fault tends to happen once warmed up.. and when you press the accelerator whilst drivng, it tends to lose power

Re: Brava 1.2 16v 2000 Engine Problems

does it semm to be using a LOT of fuel..??,
just owndering if a temp sensor is dead , and the car does'nt know it's got warm and is still driving "as if the CHOKE is still on",

getting codes read is the best proper solution..,
did you read about throttle body faults..??,
Charlie

To be honest on the fuel, i can only drive it for a couple of miles and the fault kicks in.. the after you tried to restart the engine it start fine, then the engine idle got from 1500 rpm to stall whilst not in gear...

Ian

Re: Brava 1.2 16v 2000 Engine Problems

Hello Charlie,

When i started the engine, should the stepper motor open up the butterfly valve?

because it remained closed until i pulled the accelerator cable

cheers
ian

Re: Brava 1.2 16v 2000 Engine Problems

IF this happens even when engine is cold. I would say it could be map sensor (if it uses the same inlet as the punto mk1 1.2 16v)

If only warm, then it could be lambda sensor!

Re: Brava 1.2 16v 2000 Engine Problems

again i am not sure if it's same as the punti 1.2 16v (althought) it is pretty much the same engine, it might uses a different inlet.

Mine is at the driver side near the timing belt. If you take a picture of your engine bay i could may be help point it out?

Thanks
Ming

That is indeed the map sensor.

But only replace it, if you are getting the symptoms at all temperature.

This is the exact sensor i purchased:
